天文探索的宇宙之旅
姚望星空从脚下的大地出发，穿过太阳系与恒星世界，跨越星云星团与星系之网，一路走到可观测宇宙的尽头——一套递进式天文科普课程大纲。
一切的起点在脚下。这一模块带你认识肉眼可见的天空，建立方向、时间与星座的概念，理解光与望远镜如何成为人类打开宇宙的钥匙。学完这一模块，抬头看夜空时会有完全不同的感受。
太阳系是我们最近的宇宙样本。从炙热的水星到遥远的柯伊伯带，这一模块逐一拜访每颗行星，讲清它们的个性、卫星家族与未解之谜，建立" comparative planetology（比较行星学）"思维。
理论之外，人类真正飞出去了。这一模块讲航天史与深空探测，把"探索精神"和"工程奇迹"结合起来，激发孩子对未来的向往。
恒星的一生 · 从诞生到终章！

你知道"土星扔水里能浮起来"吗？土星脑门上纹了个几何图案-北极那个正六边形风暴？为什么说土卫二冰喷泉把"生命候选"的线索？泰坦和土卫二到底哪个会有生命可能性大？听完这节可能你就知道！
木星为啥被称为“失败的恒星”？氢氦组成跟太阳一样，就差点火，质量再翻80倍才能点着。"太阳系最大的一颗行星，本质上是个差点就成了恒星的伙计",没有固体表面，就是个氢氦堆起来的球，"没法着陆，木星会先把你贴了"。自转9小时55分是太阳系最快，被自己甩成椭圆——赤道比两极胖出九千公里，接近一个地球直径。
那么到底是一个怎样的木星那？今天我们来听一下。
小行星带最大的秘密不是它有多少石头，是它有多空?柯克伍德缝隙是轨道共振——木星定期拉一把，共振轨道上的石头被甩出去，"暴脾气保安谁敢待就踹谁"?一公里以上的全找完了，一百年内没一颗会撞?用DART任务去改变小行星的轨道到底是怎么回事？听完这节你就知道了！
火星-铁锈红地表、粉色天空、蜿蜒的干涸河床，河床里叠了一层40亿年前古海洋的蓝色幻影。火星车接力赛—六轮火星车停在红色荒漠、机智号直升机悬停在上方。火星的以前到底是怎样的？听完这集你就知道了。
你抬头看月亮永远只看到同一面，背面人类几千年没见过，直到1959年苏联月球3号绕过去拍了第一张。"你可知"为什么只露一面"？月球起源大碰撞，45亿年前火星大小的忒伊亚撞了地球，崩出来的碎片聚成月球。有哪些硬核证据？月球是怎样潮汐锁定的？怎么形成的日食月食？听完这节你就明白很多！
"太阳系里表面温度最高的行星不是水星，是金星。"这个反差是核心包袱：水星离太阳最近按道理该最热，但金星更热还高30多度。直接抛出悬念，全期解答。
水星，温差600度。白天427度"你家厨房的铝锅也化了"，晚上-173度。原因是没大气，"没有被子"。然后"一天等于两年"，自转58.6天+公转88天搅在一起，太阳日176天，晒三个月天黑，再黑三个月。这是个冷知识但很准（3:2潮汐共振导致太阳日恰好是公转周期两倍）。
你知道太阳光到地球要8分钟，但从太阳核心走到表面花了—几万年！太阳燃烧的是什么？不是化学烧煤，是核反应！为什么说太阳对你来说是个延迟几万年的直播？太阳的总寿命100亿年，现在46亿中年？100 亿年后会怎样？听完这节你就明白了！
太阳系的行星分为哪几类？为什么把冥王星降级了？太阳系形成与冻结线有什么关系？太阳系的尺度模型是怎样？如果你不知道，不妨来听听这个音频，听完你就明白了！
